Square metre

(Redirected from Km²)

Categories: Units of area | SI derived units

A square metre (US spelling: square meter) is by definition the area enclosed by a square with sides each 1 metre long. It is the SI unit of area. It is abbreviated m².

A square metre is equal to:

0.000 001 square kilometre (km²)
10 000 square centimetres (cm²)
0.000 1 hectares
0.01 ares
0.000 247 105 381 acres
1.195 990 square yards
10.763 911 square feet
1 550.003 1 square inches

Square kilometer

1 km² is equal to:

the area of a square measuring 1 kilometer on each side
1 000 000 m²
100 hectares
0.386 102 square miles (statute)
247.105 381 acres

Conversely:

1 m² = 0.000 001 km²
1 hectare = 0.01 km²
1 square mile = 2.589 988 km²
1 acre = 0.004 047 km²

Note: "km²" means square kilometer and not kilo–square meter. For example, 3 km² is equal to 3 000 000 m² and not to 3 000 m².

Square megametre

Square megametres are not widely used; however, there are a number of "megametre fans" who think that this unit is very convenient for measuring oceans and continents.

1 Mm² is equal to:

the area of a square measuring 1 megametre on each side
1 000 000 000 000 m²
100 000 000 hectares
1 000 000 km²
